PoS - 3rd Training School and General Meeting of the COST Action COSMIC WISPers (CA21106)

Axions and other very weakly interacting slim (m < GeV) particles (WISPs) are easily accommodated in several extensions of the Standard Model of Particle Physics. Searches for WISPs are strongly motivated by our attempts to understand the nature of the dark matter and puzzling astrophysical and particle physics observations.

The aim of the COST Action COSMIC WISPers (CA21106) is to coordinate and support WISPs searches in a synergic way at the boundary between particle physics, astrophysics and cosmology.

The CA21106 3rd General Meeting will be held in Bulgaria. The objective of the meeting is to review the status of the activities performed by the different Working Groups and to discuss the further directions of investigations.

The COST Action CA21106 3rd Training School will be held in Annecy (France) at the LAPTh, a world-class research laboratory just 40 km away from CERN.

The goal is to start training a generation of young scientists in the interdisciplinary expertise on WISPs, ranging from theoretical and experimental approaches to multi-messenger astroparticle physics and cosmology. For this purpose, the Training School will offer lectures from experts on different aspects of WISPs physics. The School is aimed at PhD students, as well as at early-career postdocs.
